DESIGN BENEFITSTheMaster Flo Production Choke features several unique characteristics that minimize wear andmaximize durabil-

ity. The cage with external sleeve trim design creates impinging flow in the cage center, thus dissipating the fluidenergy onto itself. The external sleeve also diverts the flow upward into the flow trim (away from the outlet), contain-ing turbulence and wear within the flow trim. The valve body outlet is isolated from wear because turbulence isdissipated before flow enters the outlet, thus eliminating the typical problems of wear in the valve outlet.Another feature is the retaining sleeve which isolates the body bore from the incoming flow thus eliminating body

wear. Containment and control of wear makes the Master Flo valve ideal for high-pressure, large-pressure drop, andsevere service applications for both liquids and gases.

SEATINGMaster Flo�s Flow Trim* is designed to eliminate seat

wear and problems associated with screw-in seatassemblies. Our seating is comprised of an isolated sealingelement upstream of the throttling components, whichprotects the seat from throttling wear.Exceptional seating is provided by the self-aligned,

isolated, tapered metal seal. The collar incorporates aflow deflection lip that isolates the seat face from theincoming flow. This maintains sealing integritythroughout the trim�s service life.Master Flo provides ANSI Class VI (bubble tight) or

Class V shutoff per ANSI B16.104 1976 (FCI 70-2).

FLOWCHARACTERISTICS

*patented

FLOW TRIMMaster Flo�s Flow Trim* consists of a cage with an

external sliding sleeve. Our trim provides accurate, longlife control by using two pairs of ports in the cage. Thelower pair are small ports that provide the initial 15%control range while the upper pair are large ports thatprovide the overall capacity. This trim configurationproduces an equal-percentage flow characteristic whichoffersmaximumcontrol throughout the operating range.Our cage port configuration incorporates anexceptionally high turndown ratio providing a widecontrol range and excellent versatility. Thischaracteristic reduces the required number of trim sizesto one per body size.The top entry trim system, with the seat being

mechanically retained in place by the bonnet, providesfor ease of servicing of the flow trim. The Master FloFlowTrim system is universal between the control valveand production choke product lines.

VALVE FEATURES


PRESSURERECOVERYThe high-pressure recovery

factor (FL)throughout thecontrol range of theMaster FloChoke minimizes noise levels,flow velocities, cavitation andvalve trim wear.

CVCURVEThe Cv Curve for each valve

model is virtually identical atlower settings, illustrating theversatility of our equalpercentage trim and verifyingthe requirement for only onetrim size per body size.



MICROMETER CALIBRATION HEADMaster FloChokes are supplied*with amicrometer calibration

head to provide valve position indication to increments of 1/10of a turn for manual operation. This provides exceptionalrepeatability of valve positioning throughout the valve stemtravel.The calibration head is square with a different scale on each

of its four faces. This ensures that the valve position can bemonitored in the desired units, including Cv, bean size,millimeters or number of turns (i.e. micrometer scale).For P2 and larger chokes, the calibration head incorporates a

grease fitting to allow for lubrication of the stem threads.

STEPPING ACTUATORMaster Flo�s Stepping Actuator is available to operate our bolted

bonnet 2� and larger valves. The actuator mounts directly on thevalve cover plate to drive the valve stem nut. This feature providesfor easy field conversion from manual to automated operationwithout requiring disassembly of the valve. Supply to the actuatorcan be either hydraulic or pneumatic.TheMaster Flo SteppingActuator is designed for remote operation

of our Choke Valve. This actuator steps in 36° increments in boththe clockwise and counter-clockwise direction, providing highprecision operation.

OPERATING PRINCIPLEThe precise, durable stepping action is accom-

plished by a ratchet pawl, that engages a driveshaft, to directly operate the choke stem nut.Contact between the ratchet pawl and drive shaftis designed tomaintain full face contact during anoperating cycle. The back face on the pawl istapered to ensure that during the return cycle noloads are transmitted to the drive shaft.The pawl is spring loaded to engage the drive

shaft by dual torsion springs and is mechanicallydisengaged at the rest position to allow for reversedirection operation or manual operation.The Master Flo actuator utilizes pneumatic or

hydraulic spring-return cylinders. The operatingcylinder incorporates a self-lubricating shaft bush-ing and non-metallic piston wear ring. These fea-tures ensure the cylinder will have minimal oper-ating friction, withstand the operating loads andprovide a long service life. The vent side of thecylinder is internal to the actuator housing to elimi-nate contamination or corrosion of the cylinder
